Hello Michael,
if the font is not found, why is there not the correct indication of the
missing font ? The errormessage is in this case completly wrong.
If a fallback should be possible, it should work and not mask the
problem and create a false errormessage.
Maybe the font liberation Sans is not on a Windows10/64 machine, if this
is true i should see the message -> fpreport: Could not find the font
<Liberation Sans> in the font cache.
Or
-> EReportFontNotFound: >> Font not found: "Liberation Sans".

As I said:
The demos do not use Arial on purpose. Probably it is used as a
fallback somewhere.
So the question is: why is the demo falling back to Arial ?
It means the actually used font (Liberation Sans, line 74 of rptjson)
is not found.
Michael.
